Abstract: Objective To analyze the malaria situation in Shaanxi Province during 2005-2014, in the aim of providing reference for improving malaria elimination strategies and measures. Methods Data on malaria control and malaria epidemic reports during 2005-2014 were collected, and analysis was made on prevalence and regional distribution of malaria, species of plasmodium, diagnosis of patients, and sources of imported malaria. Results Four hundred and fifty three cases of malaria were reported in Shaanxi Province during 2005-2014, consisting of 73 local cases （16.1%） and 380 imported cases （83.9%） of which 141 were falciparum malaria （37.1%, 141/380）. Three patients died and they all were imported cases of falciparum malaria. No indigenous infection had been reported since 2011. Most of the cases were laboratory-confirmed（71.5%, 324/453）. The falciparum malaria cases accounted for 31.1%（141/453） of all the cases, and they all were imported cases. No cases of quartan malaria and ovale malaria were reported. The 73 indigenous cases distributed in 25 districts（counties） of 7 cities, including 3 cities in South Shaanxi （Shangluo, Hanzhong, Ankang）（61.6%, 45/73） and four cities in Central Shaanxi（Xi′an, Weinan, Xianyang, Baoji） （38.4%, 28/73）. The imported cases showed an increasing trend from 24 in 2005 to 59 in 2014. The 380 imported cases were mainly from over 20 countries in Africa （72.6%, 276/380）, with top sources of Angola （64 cases）, Cameroon （26）, Ghana （24）, and Equatorial Guinea （23） accounting for 36.0% （ 137/380）. The median of interval from onset to diagnosis was 5 d. The cases were mainly reported by clinical medical institutions （87.6%, 397/453）, only 7.5% （34/453） were reported by disease control institutions. Conclusion No indigenous cases have been reported since 2011, but the imported malaria cases show a trend of increase with a major source of Africa.
